As far as I can tell he's wearing a Gorka of some form, ontop of that is one of those MOLLE crossdraw-styled vests and ontop of that is a Chest Panel (Condor sells one). He also has some sort of backpack on. He has a Condor Utility/EMT pouch (Although it could be Voodoo Tactical, a lot of companies make the exact same pouch) on his leg or weaved onto his belt.

Isn't buying specifically made "STALKER gear" kind of ruining the point of making that loadout in the first place? A STALKER loadout should be old looking gear, not brand new stuff that looks like that.
